Description

[Detailed description of the invention] This invention relates to a shoulder strap belt for carrying a school bag.

Conventional school bags have had defects such as the shoulder strap belt coming into contact with the user's neck and causing pain.

Therefore, in this invention, we created a shoulder strap belt that does not touch the user's neck as much as possible, or even if it does touch the user's neck, the shoulder strap belt has a soft touch and does not cause pain. The purpose is to provide it at a low price due to easy production as it has no structure.

Hereinafter, the configuration of this invention will be explained according to the drawings shown as examples.

First, as shown in FIG. 1, the main body of this school bag consists of a left and right gusset 1, a bottom 2, a front 3, a cover 4, and a back 5.
One end of a pair of shoulder strap belts 6.6 is placed at the upper center of the back part 5, and this eyebrow strap belt 6.6
The end portions of lower strap belts 8, 8 connected via metal fittings 7, 7 are fixed to the bottom portion 2.

Therefore, as shown in FIG. 2, the layered string belt 6 has one end folded back to form an extension part 9 for fixing to the upper part of the back surface part 5, and a plurality of extension parts 9 are formed at appropriate intervals from near the other end. A pin hole 10 is formed into which a pin 11 of the metal fitting 7 can be inserted and locked.

A curved portion 12 is formed following the extension portion 9.

The back side of this curved part 12 rests on the shoulder of the user, and the concave part 13 corresponds to the neck of the user.
3, so that there is less contact with the user's neck.

Furthermore, as shown in the sectional view taken along the line A-A in FIG. 3, this shoulder strap belt 6 has a band-shaped elastic body 14 such as a sponge wrapped in a flexible cover 15, and an upper cover 16 is placed on the upper surface of the elastic body 14. However, the edge of the concave portion 13 of the curved portion 12 is covered with another elastic body 17 to form a double thick elastic body 14.17, and the upper cover is closed so that the concave portion 13 is exposed. It cuts 16.

Therefore, the edge of the concave portion 13 facing the neck is configured to be more flexible, and even if it comes into contact with the user's neck, the contact will be soft and there is no risk of causing pain or injury. It looks like it's gone.

Incidentally, since the elastic bodies 14 and 17 having the double structure are both covered by the cover 15, there is no need for sewing or pasting, and therefore, it is possible to prevent defects in this part during the manufacturing process. can.

This invention has the above-mentioned configuration, and therefore provides a shoulder strap belt for school bags that protects the user's neck, is comfortable to use, and prevents defects during manufacturing. It provides
Excellent practical effect.
